DAVID ZAIDEN, OF EAST ORANGE, NEW JERSEY.

MECHANICAL DOLL.

To all whom it may concern:

Be it known that I, DAVID ZAIDEN, a citizen of Russia, residing at East Orange, in the county of Essex and State of New Jer-' sey, have invented certain new and useful Improvements in Mechanical Dolls; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention relates, generally, to improvements 1n dolls; and the 1nvent1on has reference, more particularly,'to a novel construction of mechanically operated doll adapted to perform movements in simula-' tion of the socalled shimmy dance.

The invention has for its principal object to provide a construction of doll provided with a novel arrangement for mounting the arms in connection therewith in combination wlth a novel mechanical motor devlce for produclng a'rhythmic movement of the arms and shoulders of the doll in simulation of V the so, called shimmy dance.

1 Other objects of the present invention, not

at this time more particularlyenumerated,

will'be clearly understood from the follow-- ing detailed description of the same.

Withthe objects of the'present' invention in view, the same consists, primarily in the novel construction off-mechanical doll adapt ed to produce the movements above men- 2 tioned as hereinafter set forth; and, furthermore, the invention consists in the novel arr be 7 hereinafter more claimed. f i Y J p v r The invention is clearly illustrated in the devices and parts,

rangements and combinationsfof the various as well as in the details of the construction'thereof, all of which will fully described and accompanying drawings','in which Figure 1 1s a back view of the novel me Y chanical' doll, made according-to and embodyingthe principles of the present in 'vention.

is a detail vertical section, taken on line 5-5 in said Fig. 2.

Similar-characters of reference are employed in all ofthe hereinabove described views, to indicate corresponding parts. v 7 Referring now to said drawings, the ref erence character 1 indlcates the body of a doll, preferably made of molded material in any suitable design, and provided in its trunk portion 2 with a hollow interior or chamber 3 having openings 4 leading therefrom at its opposite sides adjacent to the shoulder portions 5. The rear wall of said trunk portion 2, which constitutes the back of the doll, is provided with a centrally longltudinally disposedopening 6.

' Adapted to be placed within the chamber porting brackets 7, which are attached there- 3, by passing the same through the opening '6, and then being secured inplace 'by supto, is the" frame 8 of a motor mechanism.

Said brackets 7 are provided at their oppoframe 8, said spindle having an outwardly projecting portion 12, which extends outwardly through the opening 6, and, upon which'is secured a winding key 13. The reference character 14 indicates a spirally wound motor spring, the inner end of which is secured to said spindlell, while the outer end 15 of which is anchored upon or fixed to the lower cross bar 16 of said frame 8.

driving clutch 18 provided with spring clutch dogs or-fingers 19. Loosely mounted on said hub portion 17" of said driving clutch 18 is a driving gear 20 provided on its inner face with clutch dog receiving pockets, or

steps 21. When the motor spring 14L is wo'undjup the rotationof the spindle isfreversed whereby said clutch, dogs or fingers 19' ride over the pockets or steps 21 of the gear 20. When the spindle is rotated by the stored energy of the motor spring 14, in the normal operative direction each clutch dog er finger 19' is engaged in a Fixed on said spindle 11-by its hub 17 is a I pocket or step 21, and so maintained in such engagement as to cause the gear 20 to be rotated with the spindle 11 and driving clutch 18. J ournaled in said frame 8 above said spindle 11 is another spindle 22 upon which is fixed a pinion 23 which meshes with and is driven by said gear 20. Said spindle 24L. Journaled in said frame 8 above said spindle 22 is a third spindle 25 which carries a pinion 26 adapted to mesh with and be driven by said intermediate gear 24. Said spindle 25 also carries a toothed escapement wheel 27. Journaled in said frame 8 above said spindle 25 is an arbor 28 upon which is fixed'an escapement dog or anchor 29, the latter. having an impulse pallet 30 at one end, and a locking pallet 31 at the other end, which alternately cooperate with said toothed escapement wheel 27. Connected with said arbor 28, so as to be oscillated transversely by the escapement mechanism,

is an upwardly projecting lever 32. Mounted on the free end of said lever 32 is a transverse bar 33, the opposite free ends of which project respectivelythrough the openings 4 of the 'trunk-portion-2 of the doll. Fixed to the outer endsof said bar 33 are the arms 34t-of the doll. Connected with said frame 8 are a pair of parallel check or momentum stop springs 35 and 36, which straddle said lever 32, so that as the latter oscillates it will alternately be engaged by said springs, whereby its impulsive movement in each direction will be checked and reversed in synchronism with the operation of the-escapement mechanism.

The operation of the doll, constructed as above described, is asfollows z-- The motor spring 14 is wound up by turning the winding key.13 to rotate the spindle 11 in the. reverse direction,thus storing the renergy of the motor spring. When the wlnding key is released the motor spring begins to unwind thereby causing a rotation of the spindle 11 in an operative direction.

The rotation of the spindle 11 is transmitted through thedriving clutch 18 to the gear 20h The driving'gear' imparts, through the intermediate train 23, 24 and 26, a rotative movement; to the escapement wheel 27 The rotation of the 'esoapement wheel 27 acts 'uponthe escape mentdog or anchor 29 to causean 0scillation oftthe same, whereby the arborv 28 is rocked to in turnoscillate the lever 32. The I lever 32, as it oscillates transversely, rocks the bar 33 whereby the respective ends of to swing. up and down,

I cethus in turn causing the arms 34 to; par-f the same .are caused take of the rhythmic movement thus produced so that the upper endsor shoulder portions 34 of said arms rise and fall rhythmically, realisticdegree the movements of, the so 22 also carries an intermediate gear v driving.

of ypinions and gear,

thus simulating to a very called shimmy dance. When the doll is V clothed the illusion is enhanced, since the movement of the arms and shoulder portions is imparted to the dress, thereby causing a swaying movement of the latter which adds considerably to the effect and life-likeness of the simulated dance. I

It will be apparent that the mechanism is very simple, and is of such a character that the dolls can be produced cheaply and with little labor.

I am aware that some changes may be made in the arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, without departing from the scope of my presentinvention as set forth in the foregoing specification, and as defined in the appended claims. Hence, I do not limit-my invention to the exact arrangements and combinations of the various devices and parts as described in said'specification, nor
